Tables are selected based on timestamp columns to obtain tables changed during a given time period and the selected tables are split into data blocks based on given partition ranges. Changes to data of the data blocks are incrementally copied into datasets. One or more tablespaces identified using a first structured query language query corresponding to a specified timestamp are unloaded based on output of the incrementally copying changes operation. Data of a source site and a target site are compared based on data blocks having the specified timestamp.
